Special Issue Information

Dear Colleagues,

Recent years have witnessed rapid progress in quantum hardware, and we are building larger and more robust quantum devices towards the fault-tolerant goal. This progress enable us to manipulate quantum information and investigate quantum physics on a real-world quantum computer, which, at the same time, presents prominent challenges for benchmarking and verification.

Quantum correlations, such as coherence, entanglement, Bell-nonlocality and magic (non-stabilizerness), play fundamental roles in quantum physics and quantum information processing. Different quantum correlations usually reflect the distinct properties of underlying quantum systems. Consequently, their characterization and detection can deepen our understanding of quantum physics. Moreover, the detection of these correlations can also serve as a benchmark, which will help us to advance the quantum hardware for information processing.

Random unitary operators, due to their elegant mathematical properties and hardware feasibility, play important roles in the study of quantum information theory, quantum computing, and quantum physics. For example, they are used in the quantum decoupling protocols in quantum Shannon theory and quantum cryptography, randomized benchmarking schemes for noisy gates, and the formalization of quantum thermalization and decoding of quantum black holes. Recently, there have also been interesting results in quantum state/channel learning with randomized measurements, non-equilibrium dynamics in random quantum circuits, and measurement-induced quantum dynamics.

This Research Topic will mainly focus on quantum correlations and random unitaries, interactions between them, and their potential applications in quantum benchmarking tools, quantum simulation algorithms, and quantum many-body physics. The main goal is to provide an active platform to share recent progress in this interesting direction, and advance further development. We welcome both original research and review articles on subjects including, but not restricted to, the following areas:

  1. Mathematical characterization of quantum correlations;
  2. Experimental detection and quantification of quantum correlations;
  3. Quantum benchmarking and learning of quantum systems with random unitaries;
  4. Applications of quantum correlations and random unitaries to quantum algorithms and quantum physics.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
